Senate committee advances NRC nominee Matthew Marzano
Marzano
The U.S. Senate Environment and Public Works Committee voted 10–9 last week to advance the nomination of Matthew Marzano to serve on the Nuclear Regulatory Commission. It was a party-line vote, with all Democrats supporting Marzano and all Republicans voting “no.”
Marzano was nominated by President Biden in July to fill the open NRC seat, and the EPW Committee held a hearing in September on his nomination. His nomination will now go to the Senate for a vote, but it is not certain whether that will happen before the end of the year, in which case his nomination process would start over in 2025.
The five-member commission has been without a tiebreaker vote since June 2023 when Jeff Baran’s term expired.

Time-of-flight ultrasonic measurements were conducted on a thick hexagonal block of 304 stainless steel irradiated to ∼33 dpa in EBR-II, and the results of ultrasonic-implied void swelling and carbide-induced densification were compared with those obtained by immersion density measurements and TEM observation. The three types of measurement were found to agree rather well with each other. This study confirmed that ultrasonic velocity measurement is a powerful non-destructive technique to measure the through-thickness-average volumetric changes induced by neutrons in thick structural materials.
